First of all, the art, rocked! Getting that as well as a pretty nice and interesting story working within 10 days is certainly an achievement. Good job to the whole team!
Dialogue system could have been a bit better, I did enjoy the dialogue between the ghost and zombie selves. I would have loved to see more interactions for each character. And the gravity/jump was a bit finicky but good job!
I loved the ghost and the zombie being the same person. I remember reading that from a reddit or one of those writing prompt generators a while back but I think this was executed perfectly!
